Application filed March 9, 1923. Serial No. 623,909.

Z 10 all whom t may concern.'

Be it known that l, RAYMOND C. HAN- cook, a citizen of the United States, residing at St. Louis, in the State or Missouri, have invented certain new and useful lmprovements in Automobile Hee. lights, of which theiollowing is a specification containing a full, clear, and exact description, reference being had to vthe accompanying drawing, forming a part hereof.

My invention consists in the novel construction and combination of parts hereinafter particularly described and distinctly claimed.

The object of my invention is to provide an improved barrel-lamp attachment for the cheaper styles orn automobile-lamps or headlights; whereby the owners of said cheaper headlights may readily convert the same into the more impressive and stylish barrellamps, by the expenditure of only about of what would be necessary for the purchase of barrel-lamps that are new throughout.

ln the drawings,

Fig. l is a sectioned side-elevation of the lamp converted in accordance with my invention, the section being taken on the vertical line 1-1 oi Fig. 2.

Fig. 2 is a front-elevation of the same.

Fig. 3 is a rear-elevation of same.

Fig. e is a detail section oi the clamping and adjusting-screw arrangement in the rear head of the barrel-lamp body, to force the converted lamp into contact with the lens or glass which will thereby be securely clamped between the front members; the section being taken on the line -fl of Fig. 3.

Fig. 5 is a fragmentary detail of the baycnet-joint used in detachably securing the front-head to the iront end ofthe barrelshell or casing, and

Fig. 6 is a detail-section of same, taken on line 6-6 of Fig. 5.

In carrying out my invention, l provide a cylindrical barrel-shell or casing 1 of sheetmetal, to the rear end of which is secured by rivets 2 or other fastening-means a rear head 3, having a large marginal-bead 4f, Vin the lower portion of which is formed a tubular-bearing 5, through which extends the bracket 6.

Said bracket 6 supports both the usual outer casing 7 and reflector 8 of the inner converted lamp, as well as the external caslar-bearing 5, into the space within said external casing 1, and is thence bent forwardly, and has its upper or forward end'xed to the exterior of said outer casing` .7 of the inner lamp.

An additional L-shaped bracket 9 supports the converted lamp at a' sufficiently forward position upon the automobile; the lower end of the first-mentioned bracket 6 being mounted at the forward end of the horizontal-arm of said additional bracket, and secured thereto by means of the usual clamping-shoulder 10 and nut l1.

The vertical-arm of said L-shaped bracket 9 is mounted in a suitable bearing in the well-known fender-iron or brace 12, and is lixed in such position by means of the usual shoulder 14 and clamping-nut 15, and the converted lamp is thereby securely mounted in the usual position upon the automobile.

Detachably-mounted upon the forward end of the said external cylindrical-casing 1,

is a front-head Vor door 16, having a marginal-bead 17 that is U-shaped in crosssection.

The inner annular-margin of said bead 17 forms a stop for therglass or lens 18 of the lamp, and said glass or lens is forcibly held or clamped in place between and in direct contact with said inner annular-margin of said bead and the front edge of the said relector 8, by means oi' adjusting-screws 19 that are threaded through a bearing 2O carv ried by the rear-head 3, and orciblyengage and press forwardly the said casing 7 and reflector 8 of said inner lamp. Fig. 4.

In the rear wall of said rear-head 3 is a central hole or passage 21, in registration with a similar central passage formed in the rear of the said inner-lamp casing 7 and in the said reflector 8, to receive the wellknown lamp-plug or mounting 22. Fig. 3.

Said front 'head 16 may be detachably connected to the casing l in any common manner, but in the present case Ihave shown the well-known bayonet-joint Jfastenings. Figs. 5 and 6. I

The said casing having formed in its front edge a plurality of bayonet-joint slots 28, which are engaged by pins 2li having their outer ends riveted or otherwise tastened in the cylindrical body 25 or" said l front head 16, so that when (as shown in Fig. 1) the said ybody is telescopicallymounted upon the said slotted outer-casing 1 and rotated thereon, the said pins will securely lock the parts together, until it is desired to unlock them to gain access to the interior of the converted lamp, when a reverse rotation will unlock them, and permit the said front head to be detached.

I claim improved transformed 4automobile headlight, comprising an external barrellamp casing; front and rear beaded-heads for said external casing; means for detachably securing the front head in place; a smaller lamp-casing yand its reflector located within said outer casing; ya glass in the front of said outer-casing; screws :threaded through Vbearings formed in the rear head of said outer casing, so that the inner ends of said screws engage and press forwardly the inner smaller casing and thereby clamp said glass in direct contact with the inner annular-margin of the bead on the said front head, and between the latter and the reflector of said smaller inner easing; a bracket-1 bearing formed in the lower portion of the bead 'of said rear head and a bracket-arm mounted in said bearing and extending therethrough into said outer casing and having its upper end secured to the back of the inner smaller casing.

In testimony whereof, I have signed my name to this specification in presence of two subscribing witnesses.

RAYMOND o. HANCOCK.
